Why Does Your Pad Leak Even When It Isn't Full?

Team WythHer · · 4 min read

A pad can leak before it's full when it has shifted out of place, when it's too short for how you sit or sleep, or when blood arrives faster than the pad can absorb it. A better fit, longer coverage and changing on time stop most leaks. If you soak through pads every 1 to 2 hours, talk to a doctor.

Ever stood up after a long lecture, walked to the washroom, and found a period stain? 😭 You check your pad, and it isn't even full. So how did that happen? Period leaks aren't always about how much your pad can hold. Very often, it's about where the blood goes before the pad gets a chance to absorb it.

Has your pad shifted?

Walking, climbing stairs, sitting cross-legged or sitting for hours can slowly move a pad out of position, leaving the edges of your underwear uncovered. Once the pad has slid forward or backward, even a light flow can miss it completely.

  • Place the pad centred, with slightly more length towards the back if you'll be sitting a lot.
  • Fold the wings firmly around your underwear so the pad can't twist.
  • Wear snug, well-fitting cotton underwear. Loose or stretched-out underwear lets the pad move.

Is your pad too short for how you sit or sleep?

When you're upright, flow goes mostly straight down. When you sit back or lie down, it can run towards the back instead, past the end of a regular pad. That's why so many leaks happen overnight or after a long sit. A longer pad with wider coverage at the back makes a big difference on heavy days and at night.

Is your flow faster than the pad can absorb?

Sometimes blood reaches the pad faster than the pad can pull it in, especially in a sudden gush when you stand up. If the top layer can't move fluid down quickly enough, it spreads sideways and escapes at the edges before the pad looks full. Pads with a perforated top layer and raised side barriers help keep that flow in the centre. (If the gush when you stand up sounds familiar, read why period blood comes out when you stand up.)

Quick fixes for period leaks

  • Match the pad to your flow: longer and more absorbent on heavy days and overnight.
  • Change your pad regularly, roughly every 4 to 6 hours, and sooner on heavy days. Here's how often you should change your pad.
  • Change before long stretches: a long class, a commute or bedtime.
  • At night, try sleeping on your back or side with your knees slightly bent rather than on your stomach.
  • Keep a spare pad and a disposal pouch in your bag for the unexpected.

How the Moody Box pad is built against leaks

Leaks were one of the top complaints we heard from the 200+ women who helped us design our pad. So the pad in the Moody Box is 290 mm long, with two upper and two lower wings to keep it in place, a side leak lock along the edges, and 200+ perforations that pull flow down and away from your skin. You can read why we built our pad this way.

When should you see a doctor?

An occasional leak is normal. Frequent leaks can be a sign of heavy menstrual bleeding, which is common and treatable. Speak to a doctor or gynaecologist if:

  • You need to change your pad every 1 to 2 hours.
  • Your period lasts longer than 7 days.
  • You pass blood clots larger than about 2.5 cm (about the size of a large coin).
  • You often bleed through to your clothes or bedding, or need two products at once.
  • You feel tired, dizzy or short of breath a lot during or after your period.

Frequently asked questions

Why does my pad leak at night?
When you lie down, flow can run towards the back of the pad instead of straight down. A longer pad with more coverage at the back, changed just before bed, usually stops night-time leaks.

Why does my pad leak at the back?
Usually because you're sitting back or lying down, so flow runs backwards past the end of the pad. Place the pad slightly further back and choose a longer pad on heavy days.

Why does my pad leak at the sides?
The pad may have twisted or shifted, or blood arrived faster than it could be absorbed and spread sideways. Secure the wings well and choose a pad with side barriers.

Is it normal to leak through a pad every day of my period?
No. If you leak through pads often, or need to change them every 1 to 2 hours, it can be a sign of heavy periods. It's worth speaking to a doctor.

A little reminder 💗

Notice when your leaks happen, check how your pad fits, and choose coverage that suits your flow. Your period is already enough to deal with. Your pad shouldn't add to the stress. ❤️
